AWS support in Amber?

So now that we can confirm group messaging is fixed, can anyone who's flashed their device confirm or deny if the announced support for AWS LTE is included as well? I have no idea when they're actually throwing the switch on the network updates but if I recall they already filed the paperwork with the fcc and so I thought they might bundle it in as long as they were releasing Amber/gdr2/group messaging all at once even if the network isn't quite ready for it yet. If it isn't included now do you think they'll hold it til gdr3 or make it a separate update.
